i ting agaiiisti the frontd'oor-jainb 9;

supports the door when open, occupies a parallel relation to the wall 1, and is sufhf ciently spaced therefrom to support the door out of contact with the Wallin approachingY or leaving its open position.- That portion ;o f";tlie rail which .liesabove the doorway inclines gradually inward from back'to front, the forward end of the saine, Y'

being directly secured tothe wall 1 just in complete theoperation "ofi closing the door,

the rear end thereof i'snmanually displaced directly inward, thereby subjectingthe rear roller `5 to a sliding displacement upon its spindle, sin'cesaid, roller will continue in engagement with the rail 7. 1A mechanism which causes` rthe rear eiid of tlie door to beautomatically engaged by certainfastening devices in assuming its closed positiony will now be described. The rear door-Jam'b 10 is interiorly formed adjacent to its front edge with avertical groove 10a receiving a rock-shaft 11, having its upper end projecting through a plate 12 into a recess in one of the roof beams, within which recess a collar 13 is fast upon'the rock-shaft. YThe lower end of the rock-shaft, after passing through a floor beam 14, is bent at aiiglit angle, and piv otally `connected with' a lever 15. supported, either mechanically or manually,

f' the lever-'15 will hang vertically "as indi- `cated vin dashlines in Fig. 1. At its `free end, the lever v15 .is formed with a slot,

which, `as the 'lever is shifted in a horizontal plane to a forwardly pointing position,

(shown inv Figs. 3 and 4) willreceive an arc-y uate-bracket 16 secured to the beam 14 beneath the middleportion ofthe doorway.,y Upon the rock-shaft 1-1,there are mounted fast three equidistant members, each formed u' 'with a shortpoin'ted protuberance 17 and a longer curved arm 18;` Upon the rear edge ofthe door 2, there are mounted three plates 19, respectively disposed at the same eleva` tions astlie members comprising the parts 17 and 18. -Each of said plates is formed with an aperture communicating with-a 1rey cess'20 behind said plate, said aperture and recessbeiiig proportioned to receive theprotuberance.. 17." having the saine elevation YVlien the door is open, the-position of the rock-shaft 11 is such that its lower end and the two members 17 and 118 extend substantially outward from thewall 1. As the rear endof the dooris being manually displaced inwardly, (after the forward end has been brought into contact 'with the jaiiib 9),y the plates 19, coming iiito contact with the Unless members.y produce a 'rotation of the rockeshaft to swing the members 17 into the recesses 20. During this displacementythe lever 15 will preferably be Amanually held `in a horizontal position so y tliat,:as the rock-shaft is turned, thejbracket 16 may be inserted inthe slot of said lever. Tosecure the 'door in its closed position, a

flock (not shown) may be engaged withy the bracket 16, after the latter has been-engaged withthe lever'15,or`a pin 21 may be passed in Figl;

through f the bracket 16 and sealed as shown Upon the front edge'of the door, there`` are mounted 'fast three angular brackets 22j, from each Aoflwhichthere projects 'a strong pin 23. Upon the door-jamb 9there are se-r cured three metallic Vsockets 24 which" extend into recessesinthe jamb `and are diss j posed at substantially the ysaine elevation as the brackets 22. As the front end 'of the door comes into contact with the jainb 9, the pins 23 will project into the sockets2f1, and after the door liasbeen fully displaced into the doorway, thepins 23 will be en-jV tirely recessed in the sockets V24, securely restricting the front end of the door against outward displacement. `,It is preferred to bevel the lateral edges ofthe doorv toward x i each other froinvfront to back, the opposite edges of the door-jambsbeing correspond. ingly'beveled. The door-jambsthus form a seat upon which-'the door may be `veryy firmly pressed kbythe leverfl and securely held through theiengagement of the lever with the bracket,` 16.@Tozincrease the refrigerating eiiiciency of a car equipped with this door, strips 25 of yfelt or other suitable packing material mayfbe fastenedv upon the 'i i f verticaly edges Vof 4the door. which strips when pressed between the f door: and render the closure'air-tight.v l

The members 17 securely'and absolutely hold the, rear end `of the door .in its closed fr position as long as the lever-15 isengaged bythe bracket' 16. lWhen it is desired to lopen the door,`the lock (not shown) or pin 21,.is removed from the bracket 16,? andthe iio lever 15 jisswung to the` rear -through fan angle of approximately ninety degrees.l `The resultingpartial rotation' of vthe rockfshaft 11 will swing lthe members y18 to outwardly pointing positions, forcing the rearend of the4 door out of the doorway,and withdrawing the members 17 from 'engagement withv the door.r After lits rear end has been out` w'ardly.,V displaced, "the door may be *readily` pushedi ori pulled -to kits *open* position. To

facilitate opening `and closing, a lhandle 26 is eXteriorly mounted Vupon the lower portion ofthedoor.' W W'henv the-door has been shifted lrearwardlywasuficientdistaiice to clearthe doorway, it will comeinto contact with a" pair :of

stop brackets 27, limiting` the lrearward motion. To prevent the door from struction may have various applications.`

swinging outwardly from the car, it will preferably be engaged at its lower edge by two suitably shaped brackets 28T' While the above-described door is especially intended for use upon refrigerator cars, it is to be understood that the con- Thus, for example, a door of this type will bevery well suited for use on cars intended to contain explosives or highly inflammable stuffs such as cotton, since the closure is so perfect as to absolutely keep out sparks `from the locomotive. i

The invention is presented as including all such modifications and changes as properly come within the scope of the following v claims.

What I claim is: 1. In a device of the character described,

the combination with a car wall formed with a doorway, of a door arranged to normally it in the doorway, formed with a plurality of recesses in one lateral edge, means normally securing the other'edge of the door against outward displacement, a vertical rock-shaft mounted adjacent to the recessed edge of the door, members mounted lfast upon the rock-shaft normally engaging in said recesses, and displaceable therefrom through a slightf'rotation of the rock-shaft, arms mounted fast upon the rock-shaft, nor'- mally closely adjacent tothe inside ofthe door, a slight rotation of the rock-shaft vCopies of this patent may be obtained forv cents each, by addressing,` the Vmeans normally securing the other edge of the door against outward displacement, a vertical rock-shaft mounted adjacent to the recessed edge of the door, members mounted in said recesses, and displaceable therefrom through a slight rotation of the rock-shaft, arms fast Aupon `the rock-shaft normally closely adjacent to the inside of the door, a slight rotation of the rocloshaft serving to displace the adjacent end of the door out-l wardly due to the resulting shifting of said arms, and a lever, pivotally connected with `the rock-shaft for manually rotating the Same.
